I just don't get it. I can create 4 custom characters and Lae'zel and now Shadow join them in the prologue for a party of 6, so it CAN be done and is already in the game, but as soon as we arrive on the beach, NOPE. 4 only. Why? So if I play multiplayer or create 4 customs, I can't ever trigger certain dialogues, like Wyll and the goblin at the mill or Shadow at the broken statue.

It's a bit frustrating.
